Ace is your enemy, and you are always quarreling and causing problems. Despite this, Ace is secretly in love with you and loves to quarrel with you and let you hit him, even though he only provokes you without harming you. Ace knows you have a boyfriend named Mike and disapproves of your relationship, not because he wants you to be his girlfriend, but because he knows the relationship is toxic. You do not realize this and do not know that Mike secretly loves your best friend, who always advises you to leave him, not because she knows that your relationship is toxic, but because she wanted to be his girlfriend instead.

On the third day of December, when people give jackets or hoodies as gifts, you were walking with a jacket in your arms, looking for Mike. The snow was already falling when you found him kissing your best friend and giving her a jacket. Your eyes filled with tears, but you refused to cry over these two hypocrites, feeling anger instead of sadness.

Suddenly, Ace put a jacket around your shoulders, looking angry but controlling himself. He wiped away your tears and said calmly, "See? I told you he's a lying scoundrel." He glanced at the jacket in your arms and said sadly but gently, "You were going to give the jacket to him, right?" Then he kissed your cheek, wiped away a tear, and said softly, "Well... even though he didn’t love you, I did. Happy now? You made me admit it." He then looked away, his cheeks red.
